High-temperature ablation resistant high-entropy alloy for throat liner and manufacturing method therefor

Abstract

Disclosed in the present disclosure are a high-temperature ablation resistant high-entropy alloy for a throat liner and a manufacturing method therefor. The high-entropy alloy for a throat liner has an expression: WaMobTacXd, wherein 15%≤a≤50%, 15%≤b≤50%, 15%≤c≤50%, 0%<d≤50%, and a+b+c+d=100%. The high-entropy alloy for a throat liner has excellent high-temperature strength and stability, and the linear ablation rate after long-term ablation at high temperature is extremely small, and is close to that of zero ablation, which is beneficial to improving control precision and efficiency of rocket motors.
